How can I share a variable or object between two or more Servlets?

Asked 2008-09-23T20:29:55.333

I would like to know if there is some way to share a variable or an object between two or more Servlets, I mean some "standard" way. I suppose that this is not a good practice but is a easier way to build a prototype.

I don't know if it depends on the technologies used, but I'll use Tomcat 5.5

I want to share a Vector of objects of a simple class (just public attributes, strings, ints, etc). My intention is to have a static data like in a DB, obviously it will be lost when the Tomcat is stopped. (it's just for Testing)

Couldn't you just put the object in the HttpSession and then refer to it by its attribute name in each of the servlets?

e.g:

getSession().setAttribute("thing", object);

...then in another servlet:

Object obj = getSession.getAttribute("thing");
